Since the first isolated attosecond pulse was demonstrated through high-order harmonics
generation (HHG) in 2001, researchers' interest in the ultrashort time region has expanded …

Attoscience is the emerging field that accesses the fastest electronic processes occurring at
the atomic and molecular length scales with attosecond (1 as= 1 0− 18 s) time resolution …

Powerful and stable attosecond pulse sources have the potential for wide application in
ultrafast science. For this purpose, we have produced a soft X-ray supercontinuum with a …

Advancements in light engineering have led to the creation of pulsed laser sources capable
of delivering high-repetition-rate, high-power few-cycle laser pulses across a wide spectral …

Ultrafast laser induced thermionic emission from metal surfaces has several applications.
Here, we investigate the role of laser polarization and angle of incidence on the ultrafast …

High-order harmonic generation (HHG) provides scalable sources of coherent extreme
ultraviolet radiation with pulse duration down to the attosecond time scale. Efficient HHG …

ELI-ALPS, one of the three pillars of the Extreme Light Infrastructure (ELI) project, will be in a
unique position to offer dedicated experimental platforms for ultrashort time-resolved …

Research at modern light sources continues to improve our knowledge of the natural world,
from the subtle workings of life to matter under extreme conditions. Free-electron lasers, for …

We present the experimental realization of spectrally tunable, ultrashort, quasi-
monochromatic extreme ultraviolet (XUV) pulses generated at 100 kHz repetition rate in a …

The interaction of electrons with strong laser fields is usually treated with semiclassical
theory, where the laser is represented by an external field. There are analytic solutions for …
